Hello lymchess

<"...."In figure 1 it is not clear that this was the intent since Dcb was not dimensioned properly"....">

The sentence should read: In figure 1 it is not clear that this was the intent, since Dcb was not dimensioned properly.

What the sentence is doing, is explaining that Figure 1 which shows a diagram with Dcb in it, the intent of the person who actually drew the figure 1 diagram, did not fully understand proper Technical Drawing Standards.

The incomplete understanding of proper Technical Drawing Standards was shown in that Figure 1, because that Dcb was not dimensioned properly.

So, either the dimensions were incorrect on that Dcb in Figure 1, or the dimensions on Dcb in Figure 1 were incomplete, or improperly done.

So.....Somewhere you have a Figure 1, with a Dcb on it.

Check carefully the dimensions of Dcb on that figure 1, and you should see an error, of some sort.

The original sentence is confusing, because of the lack of a comma, after the word: 'intent'.

Trust that explains it for you.

Kind Regards, from far away....

lymchess,

This might be an interesting topic if you can post a picture of figure 1. Sparky surely has the right answer, but it would be useful to see what the error was.

This sentence seems to refer to a previous sentence, so it would also be helpful to post the whole paragraph so that we can see the context. The "this" in the phrase "it is not clear that this was the intent" was defined previously I suspect.

Intent is short for intention.

Does that help?

For those who may not be familiar with the concept of design intent and how dimensioning and tolerancing is used to convey design intent, I will try to explain the concept. Perhaps that will help you understand what is meant here.

Say for example you have a feature, such as a seal surface or a locating ledge, who's position in relation to other features of a part are of paramount importance to the function of the part. Many drafters who are inexperienced may dimension the part in a way that tolerance can add up and allow the location of that feature to vary too much for the part to function properly, despite being machined within tolerance. The error was a failure to understand the "design intent" by the drafter and then convey that intent to the end user (the machinist). If features are important to each other, they should be dimensioned to each other instead of referencing some other abritrary point such as the end of a part which may or may not be an important surface. This is what differentiates between a true drafter and a cad operator in my opinion. To a drafter, these things are intuitively obvious, to a cad operator, they are merely lines on paper. There is far more to being a drafter than knowing how to operate a cad program.

This is a common problem with engineers as well, engineers often make for terrible drafters because, especially in the realm of parametric modelling programs, they build the models differently than how they should be dimensioned, and when the drafter imports the dimensional data from the model, they find that the dimensions reference unimportant surfaces, or to geometry that is part of an assembly elsewhere.

I would add that in reality, a drafter's job is one of data translator. We take in the language of engineering, and we translate it to the descriptive language of technical drawing. A drafter must know enough engineering to understand what the engineer is trying to convey to them and he or she must understand the way in which the end user needs that information presented to them in order to act upon it properly.

All too often this concept is lost upon those answering ads for trade schools like ITT Tech etc. who see the job as putting lines on paper.

Decades ago, a designer was someone who could operate with only a little engineering supervision and could reliably do about 80% of what a degreed engineer could do. Drafters were tasked with taking the information presented to them by the designer and making technical drawings. But somewhere along the way, being a drafter was looked upon as demeaning and a lot of HR personnell started calling what should properly be called drafters, designers. But they did not recategorize proper designers in the process, so now instead of having drafters, designers, engineers, you just have designers and engineers, and the spectrum of experience level and capability of designers is all over the map.

Hello Rorschach

To help you understand better about drafters, I attach the picture at left, of some drafters in Australia.

Trust that assists you.

Kind Regards....

This hits a point that's a problem I've seen throughout these forums... Bad, or very bad grammar being used to post questions or even answer questions posted.

It's hard enough to try to understand some of the questions asked... But when you have to make assumptions on something someone is asking, that just complicates matters even more... Not to mention the fact that the reader has to re-read it a few times at least. Anyway, for me I don't read it more than twice...

This doesn't even touch on many of the typos either... Nor does it go into, what I've assumed to be is 'leet' 'speak'(?), where the word "you" is changed to a "u" and etc.

Not to mention when people 'demand' answers but can't or won't use proper grammar; and don't even say 'thank you.'

Not to mention that many of us are 'technicial minded' people... It only takes a few moments to make corrections and clarification's to things or questions that you may need answered. Not to mention the fact that "we're" suppose to be 'professionals' here.
